DENVER — An undocumented immigrant being held in connection with a deadly hit-and-run crash has been formally charged, the Denver District Attorney’s Office announced Thursday.

Ivan Zamarripa-Castaneda, 26, has been charged with one count of vehicular homicide-DUI and one count of leaving the scene of an accident resulting in death.

Zamarripa-Castaneda was driving a pickup truck shortly before midnight on Saturday when he allegedly caused a fiery accident involving a semitruck near eastbound Interstate 70 and North Brighton Boulevard.

The crash resulted in the death of the 57-year-old driver of the semitruck. The semitruck driver has not been identified.

Zamarripa-Castaneda then fled the scene of the accident, the Denver Police Department said. He was arrested at his home in the 2600 block of West Bayaud Avenue early Sunday, prosecutors said.

According to a probable cause affidavit, Zamarripa-Castaneda’s speech was slurred and his breath had a moderate odor of unknown alcohol.

He was taken to Denver Health Medical Center where three blood draws were conducted. The results are pending, police said.
